This invention relates to a new and useful device in the nature of a brake purticularly ode ted for use in connection with motor vehicles tor the purpose of providing a rncens ott stopping the said motor vehicles.

The object ot the invention is to provide e, brnlre for motor vehicles of novel construction and arrangement of ports, hereinntter more tully described, claimed, and illustrnted in the accompanying drawing, in which 2 l 'ig, Tl shows e top plan view of my improved brohe ett-cched to or motor vehicle wheel,

Fig. thereot,

Fig; 3 shows on enlarged sectional view ot the method of uttnching the brake lining, no embodied in my improved device.

t shows it similar view to that illustrnted in Fig", 3 of n modification of the method of nttechmg the brake lining.

Fig. 5 is on end view of a brake shoe embodied, in my invention.

The inner tube 10, the shoe ill, or tire, is mounted on the rim 12, which is attached to the feline bond 13, provided with the spokes l h hub end flange 15, and etteched to the axle 16 by the nut 17. The side it, is rotntively mounted on the bearing 1%, end on similar bearings, not shown in the ecconipnnying drawing, supported by the esle housing 1'9, the above described elenients being those of a motor vehicle of comrnon construction end design, it being understood that it do not necessarily limit theuse ct my invention to the particular type of construction on shore described, but to all end clnsses of motor vehicles.

do here embodied my improved brake for vehicles comprises a brake drum 20, ct hollow circular construction, etteched, as ct 5,211, by holts, or the like, to the above mentioned spokes it, The brelre drum 20 is provided with an outer flanged element 22, hent or "formed inwardly, at an an lo thereto.

The hrnlro lining 23, is forms over the circulnr ring" member 24, end provided with extended elements end td, which are bent or termed in elongated circnin'fereiigiel a menus ot securely holding the brake lining tit, in the shoe member 27,1i have provided on outer reteiningring 28, having a tapered edge Qt, edepted to engage in the said elongated circumferential ape ture 111 the shoe 52; shows a central sectional view member 27, The outer retaining ring 28 isatteched to the shoe member 27 by the screws 30. The broke lining 23, is also atteched-to the shoe member 27, by the inner retaining ring 31, oriented to engage in the said elongcted circumferential aperture in the shoe member 2?. The inner retaining ring 31 is attached to the shoe member by screws 32 As a means of securing the desired tension on the broke lining 24:, I have provided screws 33, secured to the shoe member 27, end so positioned on to force the circular ring member 24 outwardly therefrom. It is understood that the inner and outer retaining members may be constructed in segments, so as to be easily applied to the shoe member 527.

The shoe member i2? is slidebly mounted on the shore mentioned nxle housing 19, and is normelly held in o disengaged position with the broke drum 2d, by the expansion springs 34, positioned in hollow cylindrical members 34", attached to the axle housing 19.

The rod is pivotolly attached, as at 36, to the shoe member Q7, and is similarly attached to one extremity of the bell crank 38. The bell crank 3% is pivotnlly attached to the bracket 39, supported by the axle housing. The rod 40, is pivotnlly attached, as at 41, to one extremity of the bell crank 38, and is similarly .u'tteched to the usual foot brake pedal, or broke lever, not shown on the accompanying drawing.

The above described construction is such as will permit the broke lining, 23 to be engaged with the brnlrc drum 20, when the above mentioned toot brake pednl is forced downward, or when the brake lever is pulled :Eorwerd. It is understood that both rear wheels of the hereinbetore described motor vehicle are equipped with my improved broke.

In Fig. 1 of the nccompanying drawing, the brake lining former over the circular ringehnped member 24, end isein tended over the renr of the ring shaped member 2t, which provided with circular concentric grooves til, adapted to receive the brake lining 2d, Tithe intermediate ringshaped member 5t, positioned ct the rear of the ring sheped inember 2d, and is ottached thereto, by the thrended members 7 52, bolts screws, or the like, which are also extended through the rear portion of the brake lming 23, as a means of attaching the till ill)

of said shoe,

brake wlining 23 to the ,ring-shaped members 24 and 51; The intermediate ringshaped member 51 is provided with extended concentric elements 53, positioned so as to force the brake lining 23, into the circular concentric grooves 50, so as to securely hold the brake lining 23 in place.

The, ringshaped members 24 and 51, and the brake lining 23, are attached by the threaded members 54, bolts, screws or the like, to the shoe member 27.

Having thus described my invention, what I claim as new anddesire to protect by Letters Patent of the United States is as follows 1. A brake for motor vehicles comprising a brake shoe having inner and outer circular grooves in the edge portions thereof, a ring member positioned adjacent the edge a brake lining disposed over said ring member comprising inner and out- .er extended edge portions disposed in the inner and outer grooves of said brake shoe respectively, and inner and outer rings disposed in said inner and outer grooves of said brake shoe between the edge portions of said lining and one edge of said grooves for securing said lining on said brake shoe.

2. A brake for motor vehicles comprising a brake shoe having inner and outer circular grooves in the edge portions thereof, a rin member of sand shoe, a brake lining disposed over said ring member comprising inner and outer extended edge portions disposed in the positioned adjacent the edge inner and outer grooves of said brake shoe respectively, inner and outer rings disposed in said inner and outer grooves of. ;said brake shoe between the edge portions of said lining and one edge of'said grooves for securing said lining on said brake shoe, and adjusting; screws disposed through apertures in said rake shoe and engaged with said first mentioned ring member for suitably spacing the latter apart form shoe to tension-said brake lining.

3. A brake for vehicles comprising a brake drum mounted on a vehicle wheel, an inclined flange on said drum, a brake shoe comprising a conical drum having an edge surface inclined substantially parallel to the flange of said brake drum, said brake shoe being slidably mounted on the rear axle of said vehicle, an annular member disposed between the inclined edge ofsaid brake shoe and said inclined .flange, a brake lining disposed around said annular member and secured at it sedge portions to the edge portions of said brake shoe, and means comprising spaced apart bolts screw threaded through apertures in said brake shoe and engaged with said annular member for adjustabl retaining said brake lining at a desired 'stance from the inclined flange of said brake drum and adapted to tension said brake lining.

In testimony whereof I have afiixed my signature.

FRANK CESARIO.
